layout_column_wrap {bslib}

Column-first uniform grid layouts

Description

Wraps a 1d sequence of UI elements into a 2d grid. The number of columns (and rows) in the grid dependent on the column width as well as the size of the display. For more explanation and illustrative examples, see the References section below.

Usage

layout_column_wrap(
  ...,
  width = "200px",
  fixed_width = FALSE,
  heights_equal = c("all", "row"),
  fill = TRUE,
  fillable = TRUE,
  height = NULL,
  height_mobile = NULL,
  min_height = NULL,
  max_height = NULL,
  gap = NULL,
  class = NULL
)

Arguments

...

Unnamed arguments should be UI elements (e.g., card()). Named arguments become attributes on the containing htmltools::tag element.

width

The desired width of each card, which can be any of the following:

• A (unit-less) number between 0 and 1.

  • This should be specified as 1/num, where num represents the number of desired columns.

• A CSS length unit

  • Either the minimum (when fixed_width=FALSE) or fixed width (fixed_width=TRUE).

• NULL

  • Allows power users to set the grid-template-columns CSS property manually, either via a style attribute or a CSS stylesheet.

fixed_width

When width is greater than 1 or is a CSS length unit, e.g. "200px", fixed_width indicates whether that width value represents the absolute size of each column (fixed_width=TRUE) or the minimum size of a column (fixed_width=FALSE). When fixed_width=FALSE, new columns are added to a row when width space is available and columns will never exceed the container or viewport size. When fixed_width=TRUE, all columns will be exactly width wide, which may result in columns overflowing the parent container.

heights_equal

If "all" (the default), every card in every row of the grid will have the same height. If "row", then every card in each row of the grid will have the same height, but heights may vary between rows.

fill

Whether or not to allow the layout to grow/shrink to fit a fillable container with an opinionated height (e.g., page_fillable()).

fillable

Whether or not each element is wrapped in a fillable container.

height

Any valid CSS unit (e.g., height="200px"). Doesn't apply when a card is made full_screen (in this case, consider setting a height in card_body()).

height_mobile

Any valid CSS unit to use for the height when on mobile devices (or narrow windows).

min_height, max_height

The maximum or minimum height of the layout container. Can be any valid CSS unit (e.g., max_height="200px"). Use these arguments in filling layouts to ensure that a layout container doesn't shrink below min_height or grow beyond max_height.

gap

A CSS length unit defining the gap (i.e., spacing) between elements provided to .... This argument is only applicable when fillable = TRUE

class

Additional CSS classes for the returned UI element.

Examples

x <- card("A simple card")

# Always has 2 columns (on non-mobile)
layout_column_wrap(width = 1/2, x, x, x)

# Automatically lays out three cards into columns
# such that each column is at least 200px wide:
layout_column_wrap(x, x, x)

# To use larger column widths by default, set `width`.
# This example has 3 columns when the screen is at least 900px wide:
layout_column_wrap(width = "300px", x, x, x)

# You can add a list of items, spliced with rlang's `!!!` operator
layout_column_wrap(!!!list(x, x, x))
